How To Get And Set An Item In A C# List

C# List<T> class provides methods and properties to create a list of objects (classes).

 

List is a generic class. You must import the following namespace before using the List<T> class.

using System.Collections.Generic;

List.Item

 

The Item property gets and sets the value associated with the specified index.

 

The following code snippet gets and sets the first item in a list.

using System;
using System.Collections.Generic;
namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
            // Create a list of strings
            List<string> AuthorList = new List<string>();
            AuthorList.Add("Mahesh Chand");
            AuthorList.Add("Praveen Kumar");
            AuthorList.Add("Raj Kumar");
            AuthorList.Add("Nipun Tomar");
            AuthorList.Add("Dinesh Beniwal");

            // Get first item of a List
            string auth = AuthorList[0];
            Console.WriteLine(auth);
            Console.WriteLine("-------------");
            // Set first item of a List
            AuthorList[0] = "New Author";
            foreach (var author in AuthorList)
            {
                Console.WriteLine(author);
            }
        }
    }
}

The output from above code listing is shown in below figure.
